Bug 116814 – cdemu freezes on cp with hardened kernel

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Yang Zhao 2005-12-26 14:36:46 UTC]

copying from a mounted device created via cdemu locks up system running hardened kerne

steps to reproduce:
1. cdemu 0 foo.cue
2. mount -t iso9660 foo.cue /mnt/cdrom
3. cp /mnt/cdrom/bar /tmp/

actual results:
system feezes and becomes unresponsive (at least via ssh--it's a headless machine)

expected results:
/mnt/cdrom/bar is copied to /tmp/


Only on hardened kernel--works fine for gentoo-sources

Ugh.. typoes

should be:

steps to reproduce:
1. cdemu 0 foo.cue
2. mount -t /dev/cdemu0 foo.cue /mnt/cdrom
3. cp /mnt/cdrom/bar /tmp/


also, running cdemu-0.7

not a gentoo issue
